Aldo wants to pour 26.26 grams of salt into a container. So far, he has poured 22.27 grams. How much more salt should aldo pour?

Answers

Answer: 3.99 grams

Step-by-step explanation:

You can easily break this up into 26-22 and .26-.27. 26-22 is equal to 4, while .26-.27 is equal to negative .1. 4 minus .1 is equal to 3.99, so we need to add 3.99 grams more salt to the container.

Please help and explain how to do this math problem. :c

Answers

The answer would be mode= 16, Median= 16, mean=16.91, range=8. The mode is which number on the number line has the most dots on it, in this case it’s 16. For the mode you would go from side to side and cross each dot off till you reach the middle. And once again in that case it’s 16.

mode = 16 median = 16 mean =16.9 and range=8.
